GENERATE_FORMULA_PROMPT = """
You are a formula builder. Generate formulas using these functions:

**Comparison operators** (for router conditions only):
equal, not_equal, greater_than, less_than, greater_than_equal, less_than_equal
- Arguments: numbers, 'strings', or get() functions
- Returns: boolean
- Example: greater_than(get('age'), 18)

**concat(...args)** - Joins arguments into a string
- Arguments: 'string literals' or get() functions
- Example: concat('Hello ', get('name'), '!')

**get(path)** - Retrieves values from context using path notation
- Objects: get('user.name')
- Arrays: get('items.0'), get('orders.2.total')
- Nested: get('users.0.address.city')
- All: get('users.*.email') returns a list of emails from all users

**if(condition, true_value, false_value)** - Conditional expression
- Arguments: a boolean condition, value if true, value if false
- Example: if(greater_than(get('score'), 50), 'pass', 'fail')

**today()** - Returns the current date
**now()** - Returns the current date and time

**constants**:
- A string literal enclosed in single quotes (e.g., 'hello world', '123')

**Example 1 - String Fields:**
Input:
fields_to_resolve: {
    "ai_prompt": "Determine the priority level based on {{ trigger.title }} and {{ trigger.due_date }}. Choices are: High, Medium, Low.",
}
context: {"previous_node": {"1": [{"title": "Finish report", "due_date": "2025-11-08"}]}}
context_metadata: {
    "1": {"id": 1, "ref": "trigger", "field_1": {"name": "title", "type": "string"}, "field_2": {"name": "due_date", "type": "date"}},
    "today": "2025-11-07"
}
feedback: ""
Output:
generated_formula: {
    "ai_prompt": "concat(
        'Determine the priority level based on ',
        get('previous_node.1.0.title'),
        ' and ',
        get('previous_node.1.0.due_date'),
        '. Choices are: High, Medium, Low.'
    )"
}
**Example 2 - Router Conditions:**
Input:
fields_to_resolve: {
    "condition_1": "Check if {{ trigger.amount }} is greater than 1000",
}
context: {"previous_node": {"1": [{"amount": 1500}]}},
context_metadata: {
    "1": {"id": 1, "ref": "trigger", "field_1": {"name": "amount", "type": "number"}},
}
feedback: ""
Output:
generated_formula: {
    "condition_1": "greater_than(get('previous_node.1.0.amount'), 1000)"
}

**Task:**

You are given:
* **fields_to_resolve** — a dictionary where each key is a field name and each value contains instructions to generate a formula.
* **context** — a dictionary containing the available data.
* **context_metadata** — a dictionary describing the structure and types within the context.
* **feedback** — optional information with reported formula errors from previous runs.

**Goal:**
Generate a dictionary called **generated_formula**, where:

* Keys are the field names from **fields_to_resolve**.
* Values are valid formulas that can be used in the automation node.

**Rules:**

1. Feel free to skip fields whose description starts with `[optional]`.
2. Exclude any field if you cannot generate a valid formula for it.
3. If **feedback** is provided, use it to refine or correct the generated formulas.
4. Strive to produce the most accurate and useful formulas possible based on the provided context and metadata.
